Divide by zero and you will get one

g++ -Wall -Werror -pedantic-error fname.cpp

but this didn't work

My program is going out of bounds but My compiler isn't detecting it.

sorry it shouldn't be the job of compiler to find a UB, I guess at run time.

Use valgrind and profilers

It should not, you must do it yourself
Anonymous
I don't understand you
I mean the compiler should just be compiling thing and just that and shouldn't bother what is happening at run time

I want to know is there any way to enable the flags

UB has various forms
And some can't be checked at compile-time
Ilya
Ok, isn't the compiler's job limited before run?
No, not a compiler job.
Compiler does its best to do this but it cannot find all UB

Is out-of-bounds one of those?
Ilya

Many compilers now can provide run time checks for many but not all cases of UB.
What compiler so you use?
Ilya
Ah, GCC...
Ilya
GCC is not the best here, but probably I just don't know
Ilya
Your can try MS VC Debug builds at least, or valgrind on Lin

well i am getting an error while compiling
X3eRo0
undefined reference to SetPixel@16
X3eRo0
i checked my system32 dir
X3eRo0
for gdi32.dll
X3eRo0
any idea?
X3eRo0
using mingw g++ compiler
X3eRo0
SetPixel(hdc, x, y, RGB(127, x, y));
X3eRo0
thanks i will check now
X3eRo0
Check the documentation
according to https://docs.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-setpixel?redirectedfrom=MSDN
X3eRo0
it looks cool
X3eRo0
yeah just saw that
X3eRo0
😂

i want to like print pixels to my app based on the xy coordinates
X3eRo0
so
X3eRo0
can you guys suggest a better way

i am modifying a 256*256 array of integers
X3eRo0
and i want to print those integers as colors like rgb (black-white) as each integer will be some color between black and white
Dima
Dima
Lol
Dima
bingo
X3eRo0
and the position of the color is the position of the color in the array
Tobias🐾🚲
Are you just doing rand() over it and want a pixel result from it?
X3eRo0
so is there any other way to do it without setpixel()
X3eRo0
colors[256][256] = {0,0,0,0,256,256,256,256......}
Tobias🐾🚲
so is there any other way to do it without setpixel()
Again, what precisely do you want to achieve?
X3eRo0
colors[256][256] = {0,0,0,0,256,256,256,256......}
i want to map these integers as pixels on the screen
Tobias🐾🚲
well i want to convert these pixel values to something i can visualise
